When executing the following query:

insert into #tmp_labres
select f.patientid as admissionid, f.variableid, f.sampledate, f.value, f.stringvalue, f.status
from (
select v.*, rank() over(partition by v.patientid,v.VariableID, v.sampledate order by v.SampleTime,v.resultno desc) as resultrank
from #tmp_labrestimecast v
) f
where f.resultrank = 1;

I get and ArrayIndexOutOfBoundsException. In the logs it only says "11:31:44,537 ERROR [org.teiid.PROCESSOR] (Worker15031_QueryProcessorQueue278439) yfgMWpMOgQdg TEIID30019 Unexpected exception for request yfgMWpMOgQdg.43: java.lang.ArrayIndexOutOfBoundsException
"

A few log entries before this I find a stack trace for an ArrayIndexOutOfBoundsException. Since I have executed this query multiple times I think it's a stack trace for the same query. I suppose this has something to do with the rank function. A normal select on #tmp_labrestimecast works without a problem.
